As a new BMW owner coming from a long streak of Audi vehicles I will be the 1st to say that I don't miss the 4 rings. 1st off Audi service in the DC Metro area was terrible! Dealerships provided so much misinformation and the so-called Bumper-2-Bumper warranty was a joke! My RS4 had issues with the brakes and each time Audi had me pay for labor to the tune of $1100. AoA eventually reimbursed me after Maryland's Consumer Affairs started the Lemon Law Buyback process.
I had issues with my 2011 550xi's seat wiring harness, the dealership contacted corporate and processed my buyers order for a loaded 2012 550xi MSport.
I will always support a manufacturer who stands behind their product! If you go with Audi, find a good Indy tuner and cross your fingers if you have issues!
2012 550xi MSport - everything but TV's in the head rests!
